MACHINE FOR MAKING SHOES.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed July 13, 1915. Serial No. 39,576.

To all whom it may concern:

Be it known that I, SAMUEL STRAUSS, a citizen of the United States, residing at Los geles, in the county of Los Angeles and State of California, have invented 'a new and useful Machine for Making Shoes, of which the following is a specification.

An object of this invention is to maximize the ease of making shoes and to minimize the cost of production of the same.

Another object of effect the manufacture less one-piece shoes, fort to the wearers thereof.

Another object is to provide a machine of this character which will effect the desired result in such a way as to make a shoe of absolutely seamof the desired shape and style with a minimum number of operations.

Another object is to so mount the male die that it can be tipped at an angle to the female die so that the toe portion of the former can be inserted in and retracted from the latter.

Other objects and advantages may appear in the subjoined detail description.

The accompanying drawings illustrate the invention:

Figure 1 is a vertical mid section of a mac ine built in accordance with this invention and capable of making the novel shoe, the operating parts being shown in their shoe-forming positions. Fig. 2 is a view analogous to Fig. 1, showing the male die retracted or thrown out of commission. Fig. 3 is a vertical transverse section on irregular line indicated by m w Fig. 1. Fig. 4 is a plan view partly in section on irregular line indicated by m-a:*, Fig. 1. Fig. 5 is a side view of the unfinished shoe produced by the machine shown in the preceding figures. Fig. 6 is a side view of the same shoe completed. Fig. 7 is, a side view of the shoe tion of a supplementary sole. plan view of the shoe shown in Fig. 7.

There is provided a female die 1 of suitable material such as zinc or the like mounted in a base 2 provided with a mold cavity 3 having an undercut toe portion 4 adapted to receive a toe portion 5 of a male die which is formed of sections 6, 7, the section 6 being provided with the toe portion 5 and the section 7 forming the curved heel portion that fits in the undercut heel portion 7 Fig. 8 is a this invention is to thereby insuring comshown in Fig. 6 with the addiof the female die. The die sections 6, 7 are provided with complementary inclined faces 8, 9 respectively adapted to seat against one another when the die 6, 7 is in the shoe-forming position shown in Fig. 1,

- the section 7 being provided with a tongue lOdesigned to engage a groove 11 in the face 8 of the section 6 so as section 7 from sliding relative to said section 6 when the sections are inserted in the tdie l and PILSSUIG is applied to said die secions.

The

die sections 6, 7 are loosely and yield ingly connected to one another by a loose connection such as a coil spring 12 fastened at its opposite ends to said sections respectively and designed to seat in recesses 12', 12 cut into the faces 8, 9 respectively.

The die 1 is provided with atop flatflangeforming face 13 having a groove 14 extending around the mouth of the cavity 3. Above the flat top face 13 of the die 1, there is provided a presser foot 15 having a bead 16 complementary to the groove 14;, said presser foot being provided with perforations 17 to accommodate guide rods 18 mounted on the die 1 and projecting upward therefrom.

The presser foot 15 is provided with upwardly projecting ears 19 fastened by rivets 20 or equivalent to the lower ends of diagonally extending guide rods 21 on which is reciprocatively mounted a follower 22 having ears 23 provided with perforations 24: through which said rods 21 extend. The follower 22 is pivoted at 25 to the upper ends of swinging arms 26 which are pivoted at 27 to a link 28 secured by a cap screw 29, or equivalent, to the die section 7. The follower 22 is normally supported, relative to the presser foot 15 in the position shown in Fig. 2, by coil springs 30 surrounding the rods 21 between the ears 23 and abutments 31 projecting from the guide rods 21.

The male die 6, 7 and the parts moving through an arm 32 pivoted by the pivot 25 to the follower 22 between the upper ends of the swinging arms 26. The presser foot 15 is provided with a rearwardly and upwardly inclined face 33 forming a rest and guide along which the male die slides when said die is moved up and down.

be operated still In practice to make the shoe shown at a, Fig. 6, the machine will be operated as follows: Assuming at the start that the parts are in the positions shown in Fig. 2, a piece of leather 34 previously soaked in water Wlll be placed on the flange-forming face 13 and the arm 32 will be operated to lower the presser foot 15 on to the leather to hold said Then the lever 32 will further to depress the follower 22 against the expansive force of the springs 30, to force the male die 6, 7 into the shoe-forming position as in Fig. 1, thereby pressing the leather into the desired shape determined by the form of the dies so as to form the upper 12 and sole 0 all from the single piece of leather. Then the arm 32 will be operated to raise the follower 22 or allow said follower to be forced upward by the expansiveaction of the springs 30, the

. first portion of said movement, owlng to the r the edges may sectional construction of the male die and to the loose connection between said sections, raising the section 7 and sliding. said section forward relative to the section 6 so as to withdraw the rear face of said section 7 out of the undercut heel portion 7 and further movement of the arm 32, by reason of the spring 12, withdrawing the toe section 6 from the undercut toe-forming portion 4: and at the same time raising the presser foot 15 out of engagement with the flange d of the shoe, so that the parts again assume the positions shown in Fig. 2. To complete the shoe formed as above, all that is necessary is to trim it by cutting 01f all or part of the flange d and, if desired, the upper may also be provided with a slit 6 of whlch be drawn toward one another by laces or equivalents, not shown. Thus it is seen that the finished shoe is formed of a single piece of leather and is absolutely seamless.

If .it is desired'to have a shoe with a heavier sole, a sole f may be fastened to the solecasinFig.7. l 4

I am not aware that a seamless shoe formed of a single piece of molded leather has even been known before this invention thereof and the foregoing read in connection with the drawings filed herewith will enable those skilled in the art to Which this. invention pertains to make and use said invention. I claim: I
